"Web8.3 : Ionic Radii. Ionic radius is the measure used to describe the size of an ion. A cation always has fewer electrons and the same number of protons as the parent atom; it is smaller than the atom from which it is derived. For example, the covalent radius of an aluminum atom (1 s2 2 s2 2 p6 3 s2 3 p1) is 118 pm, whereas the ionic radius of an ... " - Ionic radius of sm3+
